Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) commonly co‐occur and are associated with many negative public health outcomes. There are several etiological models that explain ...the overlap between PTSD and AUD, including shared genetic risk and phenotypic causality, but the predominant model of etiologic association is the drinking‐to‐cope self‐medication model. Although the self‐medication model is conceptually appealing and has been widely accepted within the literature examining alcohol use and anxiety (e.g., PTSD) phenotypes, the findings are inconsistent and there is a lack of rigorous empirical evidence in support of this model. This review, which was, to our knowledge, the first systematic review of the self‐medication model in relation to PTSD to date, aimed to synthesize the current literature on the association between PTSD and problematic alcohol use within the context of the self‐medication model. In total, 24 studies met the inclusion criteria for the review and assessed the self‐medication hypothesis using a variety of measurement instruments and data analytic approaches, such as mediation, moderation, and regression. Overall, the included studies provide evidence for the self‐medication hypothesis but are limited in rigor due to methodological limitations. These limitations, which include issues with the operationalization (or lack thereof) of trauma‐related drinking to cope, are discussed, and directions for future research are presented.
This study addresses not only influence and selection of friends as sources of similarity in alcohol use, but also peer processes leading drinkers to be chosen as friends more often than nondrinkers, ...which increases the number of adolescents subject to their influence. Analyses apply a stochastic actor‐based model to friendship networks assessed five times from 6th through 9th grades for 50 grade cohort networks in Iowa and Pennsylvania, which include 13,214 individuals. Results show definite influence and selection for similarity in alcohol use, as well as reciprocal influences between drinking and frequently being chosen as a friend. These findings suggest that adolescents view alcohol use as an attractive, high‐status activity and that friendships expose adolescents to opportunities for drinking.
Background
Alcohol use disorder (AUD) confers a prodigious burden of disease, disability, premature mortality, and high economic costs from lost productivity, accidents, violence, incarceration, and ...increased healthcare utilization. For over 80 years, Alcoholics Anonymous (AA) has been a widespread AUD recovery organization, with millions of members and treatment free at the point of access, but it is only recently that rigorous research on its effectiveness has been conducted.
Objectives
To evaluate whether peer‐led AA and professionally‐delivered treatments that facilitate AA involvement (Twelve‐Step Facilitation (TSF) interventions) achieve important outcomes, specifically: abstinence, reduced drinking intensity, reduced alcohol‐related consequences, alcohol addiction severity, and healthcare cost offsets.
Search methods
We searched the Cochrane Drugs and Alcohol Group Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, CINAHL and PsycINFO from inception to 2 August 2019. We searched for ongoing and unpublished studies via ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) on 15 November 2018. All searches included non‐English language literature. We handsearched references of topic‐related systematic reviews and bibliographies of included studies.
Selection criteria
We included randomized controlled trials (RCTs), quasi‐RCTs and non‐randomized studies that compared AA or TSF (AA/TSF) with other interventions, such as motivational enhancement therapy (MET) or cognitive behavioral therapy (CBT), TSF treatment variants, or no treatment. We also included healthcare cost offset studies. Participants were non‐coerced adults with AUD.
Data collection and analysis
We categorized studies by: study design (RCT/quasi‐RCT; non‐randomized; economic); degree of standardized manualization (all interventions manualized versus some/none); and comparison intervention type (i.e. whether AA/TSF was compared to an intervention with a different theoretical orientation or an AA/TSF intervention that varied in style or intensity). For analyses, we followed Cochrane methodology calculating the standard mean difference (SMD) for continuous variables (e.g. percent days abstinent (PDA)) or the relative risk (risk ratios (RRs)) for dichotomous variables. We conducted random‐effects meta‐analyses to pool effects wherever possible.
Main results
We included 27 studies containing 10,565 participants (21 RCTs/quasi‐RCTs, 5 non‐randomized, and 1 purely economic study). The average age of participants within studies ranged from 34.2 to 51.0 years. AA/TSF was compared with psychological clinical interventions, such as MET and CBT, and other 12‐step program variants.
We rated selection bias as being at high risk in 11 of the 27 included studies, unclear in three, and as low risk in 13. We rated risk of attrition bias as high risk in nine studies, unclear in 14, and low in four, due to moderate (> 20%) attrition rates in the study overall (8 studies), or in study treatment group (1 study). Risk of bias due to inadequate researcher blinding was high in one study, unclear in 22, and low in four. Risks of bias arising from the remaining domains were predominantly low or unclear.
AA/TSF (manualized) compared to treatments with a different theoretical orientation (e.g. CBT) (randomized/quasi‐randomized evidence)
RCTs comparing manualized AA/TSF to other clinical interventions (e.g. CBT), showed AA/TSF improves rates of continuous abstinence at 12 months (risk ratio (RR) 1.21, 95% confidence interval (CI) 1.03 to 1.42; 2 studies, 1936 participants; high‐certainty evidence). This effect remained consistent at both 24 and 36 months.
For percentage days abstinent (PDA), AA/TSF appears to perform as well as other clinical interventions at 12 months (mean difference (MD) 3.03, 95% CI ‐4.36 to 10.43; 4 studies, 1999 participants; very low‐certainty evidence), and better at 24 months (MD 12.91, 95% CI 7.55 to 18.29; 2 studies, 302 participants; very low‐certainty evidence) and 36 months (MD 6.64, 95% CI 1.54 to 11.75; 1 study, 806 participants; very low‐certainty evidence).
For longest period of abstinence (LPA), AA/TSF may perform as well as comparison interventions at six months (MD 0.60, 95% CI ‐0.30 to 1.50; 2 studies, 136 participants; low‐certainty evidence).
For drinking intensity, AA/TSF may perform as well as other clinical interventions at 12 months, as measured by drinks per drinking day (DDD) (MD ‐0.17, 95% CI ‐1.11 to 0.77; 1 study, 1516 participants; moderate‐certainty evidence) and percentage days heavy drinking (PDHD) (MD ‐5.51, 95% CI ‐14.15 to 3.13; 1 study, 91 participants; low‐certainty evidence).
For alcohol‐related consequences, AA/TSF probably performs as well as other clinical interventions at 12 months (MD ‐2.88, 95% CI ‐6.81 to 1.04; 3 studies, 1762 participants; moderate‐certainty evidence).
For alcohol addiction severity, one study found evidence of a difference in favor of AA/TSF at 12 months (P < 0.05; low‐certainty evidence).
AA/TSF (non‐manualized) compared to treatments with a different theoretical orientation (e.g. CBT) (randomized/quasi‐randomized evidence)
For the proportion of participants completely abstinent, non‐manualized AA/TSF may perform as well as other clinical interventions at three to nine months follow‐up (RR 1.71, 95% CI 0.70 to 4.18; 1 study, 93 participants; low‐certainty evidence).
Non‐manualized AA/TSF may also perform slightly better than other clinical interventions for PDA (MD 3.00, 95% CI 0.31 to 5.69; 1 study, 93 participants; low‐certainty evidence).
For drinking intensity, AA/TSF may perform as well as other clinical interventions at nine months, as measured by DDD (MD ‐1.76, 95% CI ‐2.23 to ‐1.29; 1 study, 93 participants; very low‐certainty evidence) and PDHD (MD 2.09, 95% CI ‐1.24 to 5.42; 1 study, 286 participants; low‐certainty evidence).
None of the RCTs comparing non‐manualized AA/TSF to other clinical interventions assessed LPA, alcohol‐related consequences, or alcohol addiction severity.
Cost‐effectiveness studies
In three studies, AA/TSF had higher healthcare cost savings than outpatient treatment, CBT, and no AA/TSF treatment. The fourth study found that total medical care costs decreased for participants attending CBT, MET, and AA/TSF treatment, but that among participants with worse prognostic characteristics AA/TSF had higher potential cost savings than MET (moderate‐certainty evidence).
Authors' conclusions
There is high quality evidence that manualized AA/TSF interventions are more effective than other established treatments, such as CBT, for increasing abstinence. Non‐manualized AA/TSF may perform as well as these other established treatments. AA/TSF interventions, both manualized and non‐manualized, may be at least as effective as other treatments for other alcohol‐related outcomes. AA/TSF probably produces substantial healthcare cost savings among people with alcohol use disorder.
The authors examined whether the perception of unequal relationship recognition ‐ a novel couple‐level minority stressor ‐ has negative consequences for mental health among same‐sex couples. Data ...were analyzed from a dyadic study of 100 same‐sex couples (200 individuals) in the United States. Being in a legal marriage was associated with lower perceived unequal recognition and better mental health; being in a registered domestic partnership or civil union—but not also legally married—was associated with greater perceived unequal recognition and worse mental health. Actor partner interdependence models tested associations between legal relationship status, unequal relationship recognition, and mental health (nonspecific psychological distress, depressive symptomatology, and problematic drinking), net controls (age, gender, race and ethnicity, education, and income). Unequal recognition was consistently associated with worse mental health, independent of legal relationship status. Legal changes affecting relationship recognition should not be seen as simple remedies for addressing the mental health effects of institutionalized discrimination.
The objective of this article is to provide an operational definition of recovery from alcohol use disorder (AUD) to facilitate the consistency of research on recovery and stimulate further research. ...The construct of recovery has been difficult to operationalize in the alcohol treatment and recovery literature. Several formal definitions of recovery have been developed but have limitations because 1) they require abstinence from both alcohol and substance use, 2) they do not include the DSM-5 diagnostic criteria for AUD as part of the recovery process (i.e., no focus on remission from AUD), 3) they do not link remission and cessation from heavy drinking to improvements in biopsychosocial functioning and quality-of-life constructs, and 4) they do not distinguish between alcohol and other drug use. The authors present a newly developed National Institute on Alcohol Abuse and Alcoholism (NIAAA) definition of recovery from DSM-5 AUD based on qualitative feedback from key recovery stakeholders (e.g., researchers, clinicians, and recovery specialists). The definition views recovery as both a process of behavioral change and an outcome and incorporates two key components of recovery, namely, remission from DSM-5 AUD and cessation from heavy drinking, a nonabstinent recovery outcome. The NIAAA definition of recovery also emphasizes the importance of biopsychosocial functioning and quality of life in enhancing recovery outcomes. This new NIAAA definition of recovery is an operational definition that can be used by diverse stakeholders to increase consistency in recovery measurement, stimulate research to better understand recovery, and facilitate the process of recovery.
The Clinician-Administered PTSD Scale (CAPS) is an extensively validated and widely used structured diagnostic interview for posttraumatic stress disorder (PTSD). The CAPS was recently revised to ...correspond with PTSD criteria in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). This article describes the development of the CAPS for DSM-5 (CAPS-5) and presents the results of an initial psychometric evaluation of CAPS-5 scores in 2 samples of military veterans (Ns = 165 and 207). CAPS-5 diagnosis demonstrated strong interrater reliability (к = .78 to 1.00, depending on the scoring rule) and test-retest reliability (к = .83), as well as strong correspondence with a diagnosis based on the CAPS for DSM-IV (CAPS-IV; к = .84 when optimally calibrated). CAPS-5 total severity score demonstrated high internal consistency (α = .88) and interrater reliability (ICC = .91) and good test-retest reliability (ICC = .78). It also demonstrated good convergent validity with total severity score on the CAPS-IV (r = .83) and PTSD Checklist for DSM-5 (r = .66) and good discriminant validity with measures of anxiety, depression, somatization, functional impairment, psychopathy, and alcohol abuse (rs = .02 to .54). Overall, these results indicate that the CAPS-5 is a psychometrically sound measure of DSM-5 PTSD diagnosis and symptom severity. Importantly, the CAPS-5 strongly corresponds with the CAPS-IV, which suggests that backward compatibility with the CAPS-IV was maintained and that the CAPS-5 provides continuity in evidence-based assessment of PTSD in the transition from DSM-IV to DSM-5 criteria.
Public Significance Statement
This study evaluated the DSM-5 version of the Clinician-Administered PTSD Scale (CAPS-5), a widely used structured interview for posttraumatic stress disorder, in 2 samples of military veterans. Results indicated that the CAPS-5 is psychometrically sound and corresponds closely with the previous DSM-IV version of the CAPS.
•Substance use and abuse has substantially increased during the COVID-19 pandemic.•Network analyses were conducted to understand COVID-19-related substance abuse.•Substance abuse was related to ...COVID-19-related traumatic stress symptoms.•Substance abuse was also related to noncompliance with social distancing.•Findings have potentially importance clinical and public health implications.
Research shows that there has been a substantial increase in substance use and abuse during the COVID-19 pandemic, and that substance use/abuse is a commonly reported way of coping with anxiety concerning COVID-19. Anxiety about COVID-19 is more than simply worry about infection. Research provides evidence of a COVID Stress Syndrome characterized by (1) worry about the dangers of COVID-19 and worry about coming into contact with coronavirus contaminated objects or surfaces, (2) worry about the personal socioeconomic impact of COVID-19, (3) xenophobic worries that foreigners are spreading COVID-19, (4) COVID-19-related traumatic stress symptoms (e.g., nightmares), and (5) COVID-19-related compulsive checking and reassurance-seeking. These form a network of interrelated nodes. Research also provides evidence of another constellation or “syndrome”, characterized by (1) belief that one has robust physical health against COVID-19, (2) belief that the threat of COVID-19 has been exaggerated, and (3) disregard for social distancing. These also form a network of nodes known as a COVID-19 Disregard Syndrome. The present study, based on a population-representative sample of 3075 American and Canadian adults, sought to investigate how these syndromes are related to substance use and abuse. We found substantial COVID-19-related increases in alcohol and drug use. Network analyses indicated that although the two syndromes are negatively correlated with one another, they both have positive links to alcohol and drug abuse. More specifically, COVID-19-related traumatic stress symptoms and the tendency to disregard social distancing were both linked to substance abuse. Clinical and public health implications are discussed.
